In all relationships, remember Matthew 5:17-18. Moses is still the reference in all matters of faith for the believers.

Matthew 5:17-18 Darby
(17)  Think not that I am come to make void the law or the prophets; I am not come to make void, but to fulfil.
(18)  For verily I say unto you, Until the heaven and the earth pass away, one iota or one tittle shall in no wise pass from the law till all come to pass.
